With over 45 years across the GTA and Ontario, our trained technicians have cleaned everything from older homes to the newer subdivisions around Thornhill. We know local ductwork and treat every home with care.
Powerful Truck-Mounted Equipment
We don’t use weak portable vacuums. Our high-suction, truck-mounted compression systems pull debris out of your home and into our truck, ensuring a mess-free, deep clean.
Health & Efficiency First
Clogged ducts force your HVAC into “overdrive,” causing brain fog, fatigue, and worsening symptoms for those with asthma or allergies. We restore your system to peak performance.

No hidden fees, no “bait and switch.” You’ll know the exact rate for your home or business—whether you’re in North Richvale or Devils Elbow—before we start.

Our reputation in Thornhill is built on word of mouth. We use drop cloths and protective gear to keep your space clean, and we back every job with before-and-after photos.

Comfort Clean’s 9 Steps Duct Cleaning Process
Serving Homes & Businesses Across Thornhill
Thornhill is really two housing stories under one name. The established pockets, Royal Orchard, Thornlea, German Mills, Grandview and the older Bayview Glen streets, are full of homes built decades ago on ductwork that has often never had a proper cleaning, so the first visit usually pulls out several pounds of settled dust and renovation debris. The newer side, the condos and townhomes around the Promenade and Centre Street, carries post-construction drywall dust that gets drawn into the return air and keeps recirculating until the system is cleaned. We clean both, right along the Yonge, Bathurst, Centre Street, John Street and Highway 407 corridors.
Thornhill straddles Markham and Vaughan, and we cover both sides of the line. Whether your home is in the Markham half or the Vaughan half, and whether it is a mature detached house or a return-air setup in a newer condo, we have cleaned enough of them nearby to know what to expect before we arrive. We also handle dryer vent cleaning and furnace cleaning for Thornhill homes and small businesses.
